Abstract:
What's already known about this topic? The overall rate of twin pregnancy is 3% with roughly 30% being monozygotic and 70% being dizygotic While the overall incidence of twin pregnancy increases with maternal age, the proportional zygosity and chorionicity by maternal age is not well established While the overall incidence of twin pregnancy increases with maternal age, the proportional zygosity and chorionicity by maternal age is not well established What does this study add? Using data from the California Prenatal Screening Program, we were able to estimate the ratio of dichorionic to monochorionic placentation by maternal age We found that both zygosity and chorionicity vary by maternal age, with an increase in the proportion of monozygotic dichorionic twins
